OpenSolaris guest boot failure "int 15h function AX=ec00, BX=0003"

[Peter Dunlap]

I recently upgraded my system with a new motherboard (DFI LanParty X48) and Intel Core 2 Q9400 processor. Host operating system is OpenSolaris build 133. Prior to the upgrade I had three guest OSes that were working fine: OpenSolaris build 132, Windows XP and Ubuntu. After the upgrade the OpenSolaris guest will no longer boot but the Windows XP and Ubuntu guests still work fine. I also tried booting an OpenSolaris live CD image which also failed. In all cases the guest appears to hang immediately after the OS is selected at the grub menu. It never actually gets to the point where it prints the Solaris banner.

I'm running VirtualBox 3.1.4 which was freshly installed from the "extra" repository after the hardware upgrade.

According to the log it looks like the last thing that happens is always this unsupported BIOS function:

00:02:33.031 Guest Log: BIOS: * int 15h function AX=ec00, BX=0003 not yet supported!

The Solaris GRUB boot loader does use that function which would explain why it doesn't actually appear to load the Solaris kernel:

But if that is really the problem I don't understand how the guest ever worked. I will attach the logfile and the output from "VBoxManage showvminfo" for the guest.
